"Three (other) little pigs..." joke

There were three little pigs named Shutup, Stupid, and Trouble, and they were driving a car through the countryside once day.Trouble leaned too far out the window and fell out of the car, and then down a hill, so Shutup and Stupid started looking for him.A police car stopped to see what was the matter, but when the cops asked what their names were, the pigs each said their names in turn."Shutup""Stupid"Misunderstanding them, the cops asked them if they were looking for trouble, and they said "Yes, he fell out of the car and rolled down the hill."
